How are fuel cell cars going to avoid these issues? They will be even less ubiquitous than solar charging stations, considering it will cost much more to build one.

Hydrogen will end up being barely cheaper than gas, too. And I don't think it will be that much more environmentally safe than gas. At least electric cars have the potential to be almost fully charged by solar power in the future.

Also, I expect hydrogen-based cars to be even more expensive than electric cars.
